Abstract

The relationship between the degree of moving away from equilibrium, the kinetic parameters and the experimental conditions is provided by solving a mass balance equation for the gaseous products of reversible decompositions. The ways to reduce the share of the reverse reaction in the total rate of reaction are discussed. The conditions of non-equilibrium CaCO3 decomposition are defined.

Zusammenfassung

Durch Lösen einer Massebilanzgleichung für gasförmige Produkte reversibler Zersetzungsvorgänge konnte der Zusammenhang zwischen der Entfernung zum Gleichgewicht und der kinetischen Parameter sowie der experimentellen Bedingungen festgestellt werden. Es werden Wege besprochen, um den Anteil der Rückreaktion an der totalen Reaktionsgeschwindigkeit zu mindern. Die Bedingungen für eine Nicht-Gleichgewichtszersetzung von CaCO3 werden gekennzeichnet.

Резюме

Выведена взаимосвяз ь между степенью отклонения от равнов есия, кинетическими параметрами и экспер иментальными услови ями путем решения уравнения ве сового баланса для газообразных продук тов обратимых реакци й разложения. Обсуждены пути пониж ения доли обратно протекаемых реакций в общей скоро сти реакции. Определены условия н еравновесного разложения карбонат а кальция.
